Radioactive Effluent Release Report for 2011

Reference:

Letter from William R. Gideon (Exelon Generation Company, LLC) to U. S. NRC,"Radioactive Effluent Release Report for 2010," dated April 27, 2011 Pursuant to Technical Specifications Section 5.6.3 and 10 CFR 50.36a, enclosed is the Quad Cities Nuclear Power Station Radioactive Effluent Release Report for January through December 2011. There were two abnormal releases that occurred during 2011. These releases, which resulted in a minor contribution to normal plant radioactive effluents, are discussed in detail in the report.In addition, pursuant to Technical Specifications Section 5.5.1.c.3 and Offsite Dose Calculation Manual (ODCM) Section 12.7.4.3.3, enclosed is the current ODCM (CY-QC-1 70-301, Revision 10) which was revised in 2011.The final enclosure (Attachment

3) is a correction to the Radioactive Effluent Release Report for 2010 which was submitted by the referenced letter.Should you have any questions concerning this letter, please contact Mr. Wally J. Beck at (309) 227-2800.Respectfully, Tim Hanley Site Vice President Quad Cities Nuclear Power Station April 27, 2012 U. S. Nuclear Regulatory Commission Page 2 Attachments:

2. Maximum Permissible Concentration a,b,c. For fission and activation gases, iodines, and particulates with half-lives greater than 8 days, allowable release limits are calculated by solving equations 2.0-5 and 2.0-6 from the Offsite Dose Calculation Manual Part II Chapter 2. The alarm setpoint is conservatively set at approximately 10% of the 1OCFR20 limit.d. For liquid effluents, with the exception of tritium and dissolved

& entrained noble gasses, allowable release limits are calculated by solving equations 2.0-1 and 2.0-2 from the Offsite Dose Calculation Manual Part II Chapter 2. The MPC values used for the monitors were as follows: Radwaste discharge 1.55E-05 jiCi/ml Service water 1.OOE-05 OCi/ml The allowable release limits for tritium and dissolved & entrained noble gases are as follows: Tritium: 3.OOE-03 uCi/mL taken from Reg Guide 1.21 Dissolved & Entrained noble gases: 2.OOE-04 uCi/mL taken from NUREG 1302 3. Average Energy The average gamma energy used to calculate the alarm setpoints for the noble gas monitors was: 9.59E-01 MeV for Quarter 1 9.61 E-01 MeV for Quarter 2 9.49E-01 MeV for Quarter 3 8.79E-01 MeV for Quarter 4 4. Measurements and Approximations of Total Radioactivity

a. Fission and Activation Gases b. lodines c. Particulates

d. Carbon-14 a,b,c. The main chimney and reactor building ventilation exhaust systems are continually monitored for iodines and particulates.

These samples are pulled every 7 days and analyzed by gamma isotopic. The particulate papers are composited every 31 days and sent to a vendor for Sr-89/90 and gross alpha analysis. Noble gas grab samples are pulled and analyzed by gamma isotopic weekly. Tritium samples are pulled and analyzed every month.Page 9 of 72 Quad Cities Nuclear Power Station 2011 Annual Radioactive Effluent Release Report Supplemental Information The Sr-89/90 and gross alpha curies released values reported are actual. On a real time basis, the portion of the "percent of applicable limit" for these contributors is reported based on projections using the previous available data.The actual results are obtained by editing the ODCM software inputs when the vendor results become available. Therefore, the "percent of applicable limits" in this report are actual.The continuous strip chart recorders for the monitors on the release points are reviewed for spikes and the activity released is calculated. An additional calculated activity for noble gases is added to the main chimney release each month. This calculation is done because most of the grab samples show less than the lower limit of detection due to the low amount of activity and the large dilution flow at the sample point. The calculation takes into account the normal offgas train and the gland sealing steam contribution to the release.The average flow at the release points is used to calculate the curies released.There are no ground level releases from QCNPS. All monitored releases are considered either elevated or mixed mode.d. Carbon-14 Quad Cities has conservatively estimated it's Carbon-14 generation and release in accordance with EPRI Technical Report 1021106, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents". The Quad Cities estimate of 2.84E+01 Ci of Carbon-14 and the resultant 2.84E+01 Ci of 1 4 CO 2 released is based upon a normalized Carbon-14 production rate of 5.10E+00 Ci/GWTh-yr, a gaseous release fraction of 1.00, a 1 4 CO 2 fraction of 1.00, a reactor power rating of 5914 MWTh (2957 MWTh/unit for 2 units), and a calculated Effective Full Power days based upon Total Core Therms data.e. Liquid Effluents The River Discharge Tanks are analyzed before discharge by gamma isotopic. A composite representative portion of this sample is saved. This is composited with other discharges that occurred every 31 days and is analyzed for tritium and gross alpha. The monthly composites are composited quarterly and sent to a vendor for Fe-55, Ni-63, and Sr-89/90 analyses. The discharge bay is sampled every 31 days and analyzed by gamma isotopic for tritium and gross alpha. It is sampled quarterly and sent to a vendor for Fe-55, Ni-63, and Sr-89/90 analysis.On a real time basis, the portion of the "percent of applicable limit" for these contributors is based on projections using scaling factors. The actual results are obtained by editing the ODCM software inputs when the vendor results become available. Therefore, the "percent of applicable limits" in this report are actual.Page 10 of 72 Quad Cities Nuclear Power Station 2011 Annual Radioactive Effluent Release Report Supplemental Information The tank volumes and activities are used to calculate the curies released for the River Discharge Tank. The total water released during the quarter and the activity is used to calculate the diluted activity released at the discharge bay, from batch discharges.

f. Estimated Total Error Percent The estimated total error percents were calculated by taking the square root of the sum of the squares of errors for sampling and measurement parameters.

g. Less than the Lower Limit of Detection

(<LLD)Samples are analyzed such that the Technical Specification LLD requirements are met. When a nuclide is not detected during the quarter, then <LLD is reported. The most conservative LLDs used for counting effluent samples are included in this report.5. Batch Releases a. Liquid 1. Number of releases: 2 2. Total time: 1.14E+03 minutes 3. Maximum time: 9.31 E+02 minutes 4. Average time: 5.72E+02 minutes 5. Minimum time: 2.13E+02 minutes 6. Average stream flow: 56.2 gpm (discharge) 2.53E+05 gpm (dilution)

b. Gaseous 1. NONE 6. Abnormal Releases a. Liquid A leak into the 1A RHR (Residual Heat Removal) heat exchanger, service water side, developed in May 2011. This produces a monitored liquid effluent release via the continuous liquid release pathway each time that the "A" loop of the Unit-1 RHR system is started. The activity identified from the leak is included in the monthly effluent calculations and is also included in the "continuous" liquid section of this report. A temporary modification to pressurize the service water side of the affected heat exchanger was installed in September 2011, which significantly reduced the leakage rate. This leak is scheduled to be repaired during refuel outage Q1 R22, in March 2013. The radioactive effluent releases from this leak will continue to be trended until after the repair.Page 11 of 72 Quad Cities Nuclear Power Station 2011 Annual Radioactive Effluent Release Report Supplemental Information

b. Gaseous An air sample taken from the doorway of the Floor Drain Surge Tank Building vestibule on September 30, 2011 was obtained due to Max Recycle Ventilation being secured. Cs-1 37 at a concentration just above detection limits was identified.

Conservative volume assumptions were used to estimate the total radioactivity released to the environment, and the overall impact is insignificant to normal station effluent, but still meets the definition of "abnormal" per Regulatory Guide 1.21, has been accounted for in station effluent calculations. This release totaled 8.OOE-04 uCi of Cs-137. This radioactivity was added to the normal monthly station radioactive gaseous effluent for September 2011.7. Radiological Impact on Man a. Liquid Dose to a Member of the Public for 2011 Total Body: 1.04E-03 mrem Organ: 2.19E-03 mrem b. Gaseous Dose to a Member of the Public for 2011 Total Body: 4.20E-02 mrem Skin: 6.87E-04 mrem Organ (Particulate/Iodine/C-1 4): 1.OOE+00 mrem The Quad Cities calculated annual doses from Carbon-14 releases have been calculated using the methodologies outlined in the ODCM. The resultant estimated releases of Carbon-14 resulted in a dose contribution of 1.24E-01 mrem/yr to organ dose (12.4%) and 3.91 E-02 mrem/yr to total body dose (93%).The maximum expected annual dose contribution from Carbon-14 has been calculated to be 2.08E-01 mrem/yr organ dose and 4.15E-02 mrem/yr total body dose. This was obtained using maximum gross thermal capacity maintained for 365 days for both units.Quad Cities conservatively calculates a "bounding dose" for gaseous effluents. The ODCM methodology determines the maximum parameters associated with each of the 16 meteorological sectors around the site. The highest of these parameters are applied to one location to determine the maximum potential for offsite doses. This calculation assumes that all available uptake pathways are present and are being used at the "maximum exposed individual" usage factors listed in Regulatory Guide 1.109. This methodology bounds the highest expected annual dose to an individual. Page 12 of 72 Quad Cities Nuclear Power Station 2011 Annual Radioactive Effluent Release Report Supplemental Information

The following pages reflect the affected original submitted page and the edited page. The edited page contains revision bars to track the changes. At the top of each page, the year of the appropriate report is outlined. The errors in the report are inconsequential. The Station Corrective Action Program was utilized to capture these errors and to provide a tracking mechanism to correct the data from the 2010 Radiological Effluent Release Report.Errata data from 2010 ARERR: 1. During review of the 2010 Radiological Effluent Release Report, it was identified that the report contained incorrect data for the following values in the Gaseous Effluent via the Main Chimney nuclide tables: annual total Sr-89 value, annual total Cs-1 37, and the particulate total activities for the 4 th quarter and annual total.* Gaseous Effluent Release Point -Main Chimney Sr-89 Reported Annual Total Value: 2.01 E-03 Corrected Annual Total Value: 1.09E-03 Cs-i 37 Reported Annual Total Value: <LLD Corrected Annual Total Value: 6.51 E-06 4 th Quarter Particulate Total Reported Quarterly Particulate Total: 4.50E-03 Corrected Quarterly Particulate Total: 1.95E-03 Annual Particulate Total Reported Annual Particulate Total: 5.42E-03 Corrected Annual Particulate Total: 4.50E-03 2. The "Liquid Effluents -- Summation of all Releases" table contained errors in the "Average Diluted Concentration" section of the tables, and are corrected in this attachment.
